• ..power button which also doubles as a lock key. It's running Windows 7, has a headphone slot, speakers in the bottom. There's a camera on the front too.

Then the video descends into farce. Or possibly further into farce. "Turn it on.." he says.

Start counting: it takes 32 seconds from him pressing that button to the screen being ready for use. Is HP or Microsoft seriously expecting people to wait half a minute every time they want to turn their tablet on before it can be used? We refer you to the instant-on that people expect and get from their phones and, well, iPads.

This doesn't stop our narrator burbling that the tablet is "very responsive, very quick". It sure doesn't look it. He goes online and brings up a browser: his attempts to make it scroll are hilarious, and he seems to open a new tab by accident. This is browsing as we don't want to know it. Then he brings up the onscreen keyboard (pressing the button, naturally): it takes up more than half the screen.

Going back a page on the browser is a swipe action: which I can't help but notice was laggy. "Pretty light, very fast," burbles our narrator, wrongly.

As John Gruber comments, "If this is real, and HP releases this thing, it's time to sell your HP stock." Engadget thinks though that "from everything we know about the tablet we're pretty sure this is the real deal".

Yet it also looks rather like something that HP did show off - see below - which is notably short on detail (it never shows how you'd activate the onscreen keyboard, or what that would look like). That opens the awful possibility that this is a real product.

In which case one can only hope that wiser heads prevail before this hits the market. Seriously, nobody deserves a tablet experience this bad.
